<p>This document lists errata items for FreeBSD 6.3-RELEASE, containing significant
information discovered after the release or too late in the release cycle to be otherwise
included in the release documentation. This information includes security advisories, as
well as news relating to the software or documentation that could affect its operation or
usability. An up-to-date version of this document should always be consulted before
installing this version of FreeBSD.</p>

<p>This errata document for FreeBSD 6.3-RELEASE will be maintained until the release of
FreeBSD 6.4-RELEASE.</p>

<p>This errata document contains &#8220;late-breaking news&#8221; about FreeBSD
6.3-RELEASE. Before installing this version, it is important to consult this document to
learn about any post-release discoveries or problems that may already have been found and
fixed.</p>

<p>Any version of this errata document actually distributed with the release (for
example, on a CDROM distribution) will be out of date by definition, but other copies are
kept updated on the Internet and should be consulted as the &#8220;current errata&#8221;
for this release. These other copies of the errata are located at <a
href="http://www.FreeBSD.org/releases/"
target="_top">http://www.FreeBSD.org/releases/</a>, plus any sites which keep up-to-date
mirrors of this location.</p>

<p>Source and binary snapshots of FreeBSD 6-STABLE also contain up-to-date copies of this
document (as of the time of the snapshot).</p>

<p>For a list of all FreeBSD CERT security advisories, see <a

Corrections</a></h2>

<p>[20080204] The ISO images of FreeBSD 6.3-RELEASE are sized for 700MB CD-ROM media (ISO
images of all prior versions assumed 650MB media). This fact should have been mentioned
in the release notes.</p>

<p>[20080204] Contrary to the release notes, ipfwpcap(8) is <span class="emphasis"><i
class="EMPHASIS">not</i></span> a feature included in FreeBSD 6.3-RELEASE. It was merged
to the 6-STABLE codeline after the release branch was created. This utility will be
included in subsequent snapshots of 6-STABLE and in 6.4-RELEASE.</p>

<p>[20080229] The release notes gave an incorrect version number for KDE. The correct
version number is 3.5.8.</p>

<h2 class="SECT1"><a id="KNOWN-PROBLEMS" name="KNOWN-PROBLEMS">4 Known Problems and
Solutions</a></h2>

<p>[20080229] A bug in Linux emulation may cause segmentation faults for some Linux
programs using <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=mmap&sektion=2&manpath=FreeBSD+6.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">mmap</span>(2)</span></a>. This
issue has been fixed on the HEAD and RELENG_6 branches.</p>

<p>[20080229, updated 20080420] Multithreaded programs that perform a <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=fork&sektion=2&manpath=FreeBSD+6.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">fork</span>(2)</span></a>
operation may crash due to a race condition in the threading library. This problem has
been fixed on the HEAD, RELENG_6, and RELENG_6_3 branches, and is addressed by errata
notice <a href="http://security.FreeBSD.org/advisories/FreeBSD-EN-08:01.libpthread.asc"
target="_top">FreeBSD-EN-08:01.libpthread</a>.</p>

<p>[20080307] When using <a
href="http://www.FreeBSD.org/cgi/man.cgi?query=sysinstall&sektion=8&manpath=FreeBSD+6.3-stable">
<span class="CITEREFENTRY"><span class="REFENTRYTITLE">sysinstall</span>(8)</span></a> to
install the X.org packages, selecting only specific components to be installed may result
in the <a href="http://www.FreeBSD.org/cgi/url.cgi?ports/x11/xorg-drivers/pkg-descr"><tt
class="FILENAME">x11/xorg-drivers</tt></a> package not being installed, and a
corresponding failure of X.org server to configure itself correctly. The recommended way
to a functioning X.org installation is simply to select <span
class="GUIMENUITEM">All</span> from the Distributions menu.</p>

<p>[20080420] A reference counting bug in the IP multicast code could cause kernel panics
under some circumstances. It has been fixed on the RELENG_6 branch by revision <tt
class="LITERAL">1.85.2.10</tt> of <tt class="FILENAME">sys/netinet/in.c</tt>.</p>
